Beit known that l, DANIEL C: STAUFFER, a

citizen of the'United Statesresiding at Canton, in the county of Starkand State of Ohio, have invented a new and useful Construction ofBuildings, of which the -following is a speciiication. l

This invention'relatesto the construction of buildings, and moreparticularly to a novel form of'mold for 4constructing the walls,partitions, `and other'portions of the building from cement, concrete,or similar plaster Inateriah The object of the invention is to provide acomparatively simple, inexpensive, and durable device of this character,in which the sev- .eral parts may be quickly and conveniently assembledand firmly maintainedin position during the molding operation, and onewhich will per-mit the' continuous operation of the mold during theformation of the wall.

' A further object of the invention is to provide aflexiible connectionbetween the several mold-sections designed to be embedded inl theconcrete or cementl and adapted to be cut or severed when the cementsets to thereby permit the removal of the mold-sections, said flexibleconnection. being lett embedded in the wall so'as to strengthen andreinforce the latter. l y

With these and otherl objects in view the invention consists in theconstruction and' novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto ap ended, it being understood that variouscllianges'in form, proportions, and minor details of construction maybe'resorted to without departingfrom the principle or sacriiicing anyof' the advanta es of the invention. n the accompanying drawings,forming a v, part of this specification, Figure 1 is a side elevation,partlyin section, of a portion of a improved mold. plan view-o the same.Fig. 3

drawings. In constructing the cement or concrete Fig. 4

wall I'employ one or more mold-sections,

each comprising an'inner wall 5 and an outer wall 6, Said walls beingreinforced and strengthened at their topy and bottom edgesv bylongitudinally-disposed L-shaped angloirons 7, to which said walls areriveted or otherwise rigidly secured and which also serve to support theseveralmold-sections in vertical alinement durinor the formation of thewall.

The outer walls 6 of the mold-sections are preferably oblong iri shapeand stamped, pressed, or otherwise rou hened, so as to give the exposedsurface' of diie wall the appeax'-, ance 4oi cut or chi )ped rock, thelongitudinal v.edges of the wa s 5 and 6 being bent or curved inwardly,as indicated at S, to produce inwardly-extending flanges lwhich formdepressions in the wall and serve 'to define the several blockscomprising the latter.4 ll desired, however, some of theplatescomprising the outer wall 6 may be smooth or unobstructed, asindicated at 9, whereby certain ofthe blocks in the wall will present asmoothdressed surface, thereby adding to the ornamental ap earance ofsaid wall.

v The ang e bars or irons 7 are provided with a plurality of spacedopenings 10, adapted to register with each other when the mold-sectionsare disposed in superposed relation, 'as shownin Fig. 3, said openingsbeing designed to-receive coupling-y pins or members 11,

which also serve asa means for fastening the -ends ofthe transverseconnecting-wires or `tie-rods 12.

The wires or tie-rods 12 temporarily retain the lower ends ofthe walls 5and 6 in engagement With the adjacent faces of the molded `-Wall 13during the formation of the latter and until the cement, concrete,or-other Ina.-

terial sets or hardens, when the wires are' cut or severed close to thewall to permit the removal of the mold-sections, and said wires leftembedded in the cement so as to rein s force and strengthen the wall.

The side walls of the several mold-sections are secured in spacedrelation to each other by means of a transverse channel-bar 14, having aseries of spaced openings 15 formed in one end thereof and provided fatits opposite end with a depending ivoted clamping member 16. The free enof the clamping member 16 is designed to bear against the angle-bars 7of the mold-sections, while its opposite end is provided with alaterallyfprojecting head 17, which extends a shortdising-wires fastenedto the heads of the pins, -as

v dows of the building, the outer wall 6 Aof the vthe pins 11, thecement, concrete, or other tance alcove the bar i4 to .permit theinsertion of a loclringwedge or key 18. Slidably' mounted between ,thedepending ilanges 19 ofthe bar 14 is a movable clamping member 20,adapte'd'to engage the angle-bars on the inner walls ofthemold-sections, said clamping member being adjustable longitudinally ofthe bar 14 to ermit the formation of walls of diii'e'rent thicknessesand securely locked iii-adjusted position by a lbolt or similar`fastening device 21, passing'through one of the openings in the bar-14and engaging a corresponding opening 22 in the angular extension -23 ofsaid clamping member, as shown. In ractice the lower mold-section isirst place in position, with-the pivoted ends of the sliding clam ingmembers engaging the angie-irons 7, a er .which 'the wires 12 arestretched across the top .of the mold` and the ends thereotcoiled or:otherwise fastened to plaster material being subsequently shoveled orotherwise introduced between the' walls of the mold and thoroughlytamped.4 The upper mold-section is then placed uponthe lower section andthe ends ofthe connectbest shown in Fig. 3 of the drawings. After thecement in the lower mold-section has set or hardened the iiexiblewiresconnecting the lower ends of the side walls are cut or severedclose to the surface of the cement, which permits the ready detachmentof said lower section, the Wires being left embedded in the wall,thereby reinforcing and strengthening the latter and permitting thecontinuous operation oiithe mold during the formation of said Wall.

'In some cases the walls may be formed with vertical iiues orair-.chambers 24 by' p0- sitioning suitable core members 25 between theside walls of the mold-sections and elevating or drawing said coresupwardly as the hei ht of the wall increases.

lgn Fig. 4 of the drawings there is illustrated a section of a mold forconstructing that portion of the wall adjacent to the winmold beingformed with an auxiliary moldsection 27 forforming the window-sill. Inthis case a wooden nailin -block 28 is inserted between the side wal ofthe mold, to which maybe secured the window-casing 29, there being alsoa pair of core members 30, carried by a 4metal plate 31, positionedbetween-said side walls, for `forming suitable openings for thereception of the sashweights of the Window.

From the foregoing .description it willbe seen that there is provided anextremely simple and inexpensive device admirably adaptd for theattainment of the ends in view.

pins, said rods being adapted to be severed 1 and left embedded in theconcrete when the mold-sections are removed.

2. A mold comprising a plurality of moldsections, a bar extendingtransversely across the top of said sections, a depending clampingmember slidably mounted on the bar at one end thereof, a clampin memberpivoted to the opposite end of thegbar and provided withv alaterally-extending head, and a locking-key adapted to engage said headand bar, respectively, for forcing the clamping memmold-sections.-

A mold consisting of a plurality of s uperposed mold-sectionseachcomprising an outer and an inner wall provided with longitudinalreinforcing-'bars adapted to engage the reinforcing-bars of adjacentsections, a perforated barextending transversely across the uppermold-sectionsfa depending clamping member slidabl e end thereof anadapted to engage the reinbers into engagement with the adjacent'mounted on the bar at one Y p -9'5' forcing-bar on one of the walls ofthe adja-.

4. A mol for concrete-.constructions comprising a-plurality ofsuperposed mold-sections each provided with -perforated;` longitu-ydinally-disposed angie-ironsf. adaptedto-qengage the angle-irons ofad'ac'ent ,mold-sec? tions, removable pins seate in saidA perforat1onsand servln to alineadjacent mold-sec- IIO.

tions, and iiexi le tie-rods connecting the"A Y mold-sections and havinfastened to said pins, said rods being adapted to be severed and leftembedded -in the concrete when the mold-sections are detached.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.
